The Effect of Dairy on Bone Mass and Body Composition in 4th-8th Grade Boys and Girls (B3)
May 3, 2018 updated by: Berdine Martin, Purdue University
Influence of Dairy on Bone Accrual and Bone Size and Fat and Lean Mass in Early Pubertal Overweight vs. Healthy-weight Boys and Girls
Building stronger bones during pubertal growth could reduce lifelong fracture risk.
This project is an 18 month dairy intervention study for overweight and healthy weight 4th-8th grade boys and girls.
Half of the girls will receive dairy products to add to their habitual diet (milk, yogurt, and cheese) to equal three products per day, while the other half will remain on their normal diet.
All participants will attend four study visits, each 6 months apart.
At these visits height, weight, bone density and geometry, and fat and lean mass will be measured.
This study aims to show that meeting calcium requirements by eating dairy products builds bigger, stronger bones, and that this effect may be enhanced in overweight boys and girls.
The effect of the dairy intervention on body fat, lean mass, and weight, as well as the mechanisms and predictors of changes in bone mass and size and body composition will also be evaluated.
